Global fossil CO2 emissions are projected to decrease by 0.4% in 2026, reaching 38.2 billion tonnes, according to the Global Carbon Project. The decline is attributed to rapid expansion of solar and wind power, electric vehicles, and the Iran conflict’s energy shock, which reduced oil emissions by 1.9%. However, clean energy growth remains insufficient for a sustained emissions peak.
Total CO2 emissions, including land-use change, are projected at 43.3 billion tonnes — up from 42.8 billion in 2025. The remaining carbon budget for limiting warming to 1.5°C is now 150 billion tonnes — less than four years of current emissions. Natural carbon sinks, like forests and oceans, are recovering but face threats from the 2026 El Niño.
Experts emphasize that structural change, not short-term shocks, is needed for lasting emissions reductions. China’s emissions are projected to fall 0.9%, led by drops in oil use. Over 90 institutions contributed to the research, published in Nature Climate Change.
